To reach Fire God Mountain, you need to travel to the first page of Tiki Isles, where you'll spot a burning, animated volcano in the north. To get in, you're going to need 5 tubes of SPF-3000. To note, you'll start with 6 tubes for free, but it won't be enough on the long dig down, so you've gotta use Wall posts (those tubes aren't giftable) to request more from fellow players.

Beating the Mountain maps requires completely new strategies and tools. There are 14 levels to explore. Fruits-wise, only Lava Mangoes will work in the mountain for energy replenishment. (You can also use Energy Packs.) Instead of dumbly plowing through every tile, you'll need to dig SMART and FAST.

For more info, check out the "Volcano FAQ" tab on your Treasure Island window, and the newly updated Fire God Mountain Info Thread at the Zynga forums. Click here to launch the game and get digging!
